Study Notes

Statistics in Assessment

Descriptive statistics report or describe the features or characteristics of data
Inferential statistics generalize about a larger population based on sample data
Non-parametric statistics are another type of statistics
Errors can occur in the assessment process, including sources of error

Inferential Statistics

Characterized by using sample data to generalize about a larger population
Example: Dr. Ubaldo uses sample data to generalize about a larger population in his study

Measures of Central Tendency

Mode is the most frequently occurring value in a dataset
Median is the middle value in a dataset when it is in order
Mean is the average value in a dataset
Example: Find the mode in the dataset: 44, 45, 46, 37, 45 → 45

Descriptive Statistics

Primary concerns in descriptive statistics include mean, mode, and standard deviation
Example: Dr. Rivera wants to know the standard deviation of scores in his self-made test on the Filipino trait, Pagkamahiyain

Testing and Assessment

A score can be a letter or other codes that represent the performance quality of a test
Interview as an assessment tool can be ideal since a wealth of information is being obtained
Panel interview involves more than one interviewer participating in the assessment process
Portfolio assessment is mainly concerned with the work products of an individual

Psychological Concepts

Traits refer to discernible, comparatively permanent differences between two individuals
Psychological state refers to a person's temporary emotional or mental condition
Example: Mary, a very quiet person, acts like a "saint" around her friends and consistently lives by her values in life

Psychometric Concepts

Norms are standards or benchmarks used to evaluate and interpret individual test scores
A sample is a subset of individuals from a larger population
A population is the complete universe of individuals with at least one common, observable characteristic
